Suspended solids in an aquatic system are generally small particles &lt;100 microns of undigested or partially digested food, bacteria, algae, clay and silt suspended in the water column. \u00a0Fine suspended solids case gill irritation and reduce the clarity of the water, whereas large organic particles create a serious waste load problem by consuming tremendous amounts of oxygen, adversely effecting the water quality. \u00a0Bead filters remove suspended solids by at least four different mechanisms as water is passed through the packed bed of beads. Particles &gt;100 microns are subjected to <strong>physical straining<\/strong>. For slightly smaller particles(50-100 microns) the dominant mechanism is <strong>settling<\/strong>. Suspended particles (5-50 microns) are removed by <strong>interception<\/strong>, a subtle process caused by collisions between the particle and the bead media surface. Finer particles (&lt;20 microns) are removed through <strong>bioabsorption<\/strong>, the capture of particles by the bacteria biofilm. Bead filters are excellent clarification units, capable of maintaining display quality water at high waste loading rates. Studies have shown that <strong>AST bead filters capture 100% of particles &gt;50 microns and 48% of particles in the 5-10 micron range per pass.<\/strong><\/p>\n<h3>Better Than Sand<\/h3>\n<p>Bead Filters were originally invented to overcome some of the major problems with using sand filters.

These media stand apart from traditional bio-elements in their open profile which provides optimal conditions for maintaining a thin active biofilm on the surface. It is important to bear in mind that it is the active surface area that counts. This is the area that in practice can be utilized for bacterial growth and dictates the performance.
